Concrete gravelboards, or kicker boards, can be used as retainers or to keep your timber panel off the floor and away from moisture. The gravelboards can also be stacked to create a solid concrete panel. Available in 12″ high boards ( 6″ only in plain finish ). All gravel boards are 6′ wide Note – any hairline cracks will not affect the strength of the gravel boards. These cracks may appear due to the curing process and are not a defect.
